Abstract
The purpose of this study was to determine serum Cu, Zn, Mn, K, and Mg levels before and during pregnancy and during the lactation period of sheep and cattle and to determine the relationships between periods. For this purpose, blood samples of 14 healthy, pregnant Brown Swiss cows fed under normal condition and 36 Karakaş (İvesi × Akkaraman) sheep were used. Blood samples were analyzed using an atomic absorption spectrophotometer. There were significant differences between before pregnancy and during pregnancy, and during pregnancy and the lactation period for serum Zn concentration; also before pregnancy and during pregnancy, and before pregnancy and the lactation period for serum K concentration in cows (p<0.05). There were significant differences between before pregnancy and the lactation period for serum Cu concentration, and before pregnancy and during pregnancy for serum K concentration; also pregnancy and the lactation period for serum Mg concentration in sheep (p<0.05).
